An integrated circuit includes at least four linear-shaped conductive structures formed to extend lengthwise in a parallel direction to each other and each respectively including a gate electrode portion and an extending portion that extends away from the gate electrode portion. The gate electrode portions of the linear-shaped conductive structures respectively form gate electrodes of different transistors, such that at least one of the linear-shaped conductive structures forms a gate electrode of a transistor of a first transistor type and does not form a gate electrode of any transistor of a second transistor type, and such that at least one of the linear-shaped conductive structures forms a gate electrode of a transistor of the second transistor type and does not form a gate electrode of any transistor of the first transistor type. Extending portions of the at least four linear-shaped conductive structures include at least two different extending portion lengths.
